Fix corner case bug in Pgpool-II starting up.

It is possible that a failover request is accepted before primary node
is searched.  This leads Pgpool-II to a strange state: there's no
primary node if the failed node was a primary node (even if new
primary node exists as a result of promotion of existing standby).

See [pgpool-hackers: 2321] for more details.
